docs: centralize documentation into helpdoc

Problem: documentation was spread across four files (README.md,
doc/oil.txt, doc/api.md, doc/recipes.md) with duplication and gaps.
User events were undocumented, and adapter docs only lived in the
README.

Solution: expand doc/oil.txt with five new sections (introduction,
requirements, adapters, recipes, events) from existing content. Trim
README to a landing page pointing to :help oil. Delete doc/api.md
and doc/recipes.md since their content now lives in the helpdoc.

Closes: barrettruth/oil.nvim#6

+Install with your favorite package manager or with luarocks.
 
-```console
-luarocks install oil.nvim
+## Quick start
+
+Add the following to your init.lua
+
+```lua
+require("oil").setup()
 ```
 
+Then open a directory with `nvim .`. Use `<CR>` to open a file/directory, and `-` to go up a directory. Otherwise, just treat it like a normal buffer and make changes as you like. Remember to `:w` when you're done to actually perform the actions.
+
+If you want to mimic the `vim-vinegar` method of navigating to the parent directory of a file, add this keymap:
+
+```lua
+vim.keymap.set("n", "-", "<CMD>Oil<CR>", { desc = "Open parent directory" })
+```
+
+You can open a directory with `:edit <path>` or `:Oil <path>`. To open oil in a floating window, do `:Oil --float <path>`.

+    Before performing filesystem operations, Oil displays a confirmation popup to ensure

+        * contain no deletes

+    2. You copy a directory to a new location, then you enter the directory and make
+       changes before saving.
+
+    In case 1, when you edit the file you are actually editing the original file because
+    oil has not yet moved/copied it to its new location. This means that the original
+    file will, perhaps unexpectedly, also be changed by any edits you make.
+
+    Case 2 is similar; when you edit the directory you are again actually editing the
+    original location of the directory. If you add new files, those files will be
+    created in both the original location and the copied directory.
+
+    When this option is `true`, Oil will prompt you to save before entering a file or
+    directory that is pending within oil, but does not exist on disk.
